To all whom it may concern.-

Be it known that LBENJAMI C. ANDERSON, acitizen of the United States,residing in the borough of Brooklyn, in the city and State of New York,have invented a certain new and useful Improvement in Bushing-Valves andFaucet-Couplings, of which the following is a- It has long been commonto provide ametallic bushing for barrels carrying a valve in itsinterior which is operable from the outside, with provisions forattaching a coupling and for opening the valve by the same mo tionthereof which attaches it to the bushing. The presentinvention involvesthat construction and mode of operation. I have devised importantimprovements, one of which is to make the bushing with the exteriorportion of brass and the inner portion of soft metal.

It has long been practiced in certain arts to cast in a mold a singlearticle of two different metals, introducing one before the other underproper conditions to effect a permanent junction. I have discovered thatsuch mode of manufacture applied under proper conditions and with propermetalswillproduce a faucet-bushing having a hard exterior to allow roughusage of the barrel and presenting to the interior contents of thebarrel only a soft-metal portion which is economical in material andlabor and shall not be affected by any acid.

I have also made important improvements in the form and construction ofthe parts in other respects, as will be set forth below and pointed outin the claim.

The following is a description of'what'I consider the best means ofcarrying out the invention.

The accompanying drawings form a partof this specification.

Figure 1 is a central longitudinal section of the hard-metal portion ofmy bushing. This figure also shows in elevation the plug in the relationwhich it assumes after the bushing has been added to and finished. Theplug is in the closed position. Fig. 2 isacorresponding section throughthe completed bushing and all the associated parts. The plug is in theopen position. Fig. 3 is an end view as seen from the right in theclosed position. Fig. 4 shows the same in the open condition,

and Fig. 5 is a side view of the coupling and key.

Similar letters of reference indicate corresponding parts in all thefigures where they appear.

' A is aportion of the barrel, usually the mid-length of a stave,inwhich the bushing is inserted and is permanently retained.

B is the exterior portion of the bushing, formed with an internalextension B. C is a further extension of soft metal permanently united,so as to serve as a unit, with the brass portion B B of the bushing. Inthe extension 0 are liberal apertures c on opposite sides, which whenthe plug is properly turned admit the liquid to be discharged. Themidlength and inner portion of the bushing is bored conically, as shown,the smaller end outward toward the exterior of the barrel.

D is the plug, having its corresponding portion tapered, as shown, so asto make a tight and easy fit and having apertures d, corresponding tothe apertures c in the bushing. These communicate with the passage d inthe center, which extends to the small end of theplug. The large end ofthe plug is closed and is recessed and receives the inner end ofahelical spring E. Acorresponding disk G, recessed in its inner face,receives the other end of the same spring. This disk is held adj ustablyby screw-threads G in the bushing and may be set in or out by the aid ofa forked key (not shown) engaging in the holes g.

The compound bushing B B C has longitudinal grooves 19 in its interior,from the bottom of each of which extends a partially-circumferentialgroove 1 There are two of the spline grooves 17 on opposite sides of theaxis and two of the connected grooves b. The latter are slightlyinclined, so as to draw inward the coupling when it is inserted andpartially revolved, as will appear farther on. The outer end (thesmaller end) of the plug is peculiarly formed. It serves to engage withthe coupling-piece'and key by the aid of deep open slots 61*. (See Figs.1 and 2.)

- H is the coupling and key. It is provided with a flange H, fittingtightly against the outer face of the bushing. H H are stout projectionson opposite sides, which when the coupling is engaged with the bushingare ICO received in the slots d of the plug and extend outward throughsuch slots into the bushing. As the coupling is introduced theseprojections H are received first in the splinegrooves 11 of the bushing,and as the coupling is thrust farther inward it enters the outer end ofthe plug, the coupling matching within the plug and the projections Hmoving along the straight open slots (Z When it has been thrust in tothe full extent required, the flange H matches tightly against the outerface of the bushing. Then the turning motion is commenced, and theseprojections H remaining engaged in the slots d and thereby turning theplug D, also extend out into the bushing and are by the turning motioncarried into the slightly-inclined partially-circumferential grooves 17,and thereby lock the coupling.

In the construction of the bushing the soft metal is brought intopermanent union with the brass by placing the previously-cast portion Bin a mold and, having warmed the whole, pouring soft metal to fill theremainder of the mold and form the required unitary structure. smoothlyand easily bored and in assembling the plugis introduced, followed bythe spring, and on applying the disk G and screwing it up to a gentlecontact with the spring the device is ready to serve for an indefiniteperiod.

The liability of brass faucets to form verdigris is an objection to theuse of brass as the material for faucets for manyliquids, among whichare the whole line of fermented and brewed beverages. However carefullythe metal is tinned, expense is involved in such defence, and the brassis always liable to be imperfectly tinned or to be exposed to corrosionby the removal of the whole or a part of the coating. It is a commonbelief among those in the trade that vinegar, which is oftenintentionally or unintentionally produced in the contents of thebarrels, will in time remove the ordinary thin coating. My faucet havingthe entire main body and inner end of white metal insures against anypossible exposure of brass to the contents of the barrel.

My construction insures that the plug shall be in the closedpositionbefore the coupling can be withdrawn, and the same conditionsinsure that all the parts shall be in position to again receive the sameor a similar coupling when required. The turning of the coupling in onedirection engages the coupling strongly and tightly with the barrel andalso turns the plug in the required direction to allow the flow of theliquid. It may serve The soft-metal portion 0 isperfection and issimpler and less liable to derangement than any previously known to me.It requires no packing.

K is a perforated shell formed separately and applied as a strainer overthe inner and mid-length portions of the bushing. It is engaged with thebushing by screw-threads at K. When used with ale or other liquidcontaining solid or semisolid matter, this shell presents a largefinely-perforated surface, through which the liquid is certain to findsufficient entrance even if .many of the apertures are stopped.

I can avoid much of the labor of boring the soft metal by using an ironor other hardmetal core, finely finished, of the proper tapering form.

Some of the advantages due to certain features of the invention may beseparately enumerated as follows: By reason of the fact that the bushingis composed of two metals formed in a single rigid part by casting thesoft metal 0 upon the brass B B,I am able to have the outer part of amaterial which maintains its smooth condition when the barrel is rolledover nails, stones, or other hard irregular surfaces to allow it to bekept in condition for an indefinite period to receive the flange H ofthe coupling H and make a tight joint therewith, while the structure isproduced in high perfection at less cost than if it were all brass and,above all, can present to the interior of the barrel under no conditionsany but the harmless surface of the soft metal which constitutes themain body and inner end of the bushing.

I claim as my invention- The bung-bushing B B C, composed of two metals,the outer part B B of brass and the inner and main part 0 of soft metalcast together and adapted to serve substantially as herein specified.

In testimony that I claim the invention above set forth I affix mysignature in presence of two witnesses.
